Chapter Chapter 7 in Mathematical and Computational Modeling of Tonality, 2014, pp 109-130 from Springer

Abstract: Abstract This chapter describes an $$O(n)$$ algorithm for segmenting music automatically by pitch context using the Spiral Array, a mathematical model for tonality, and applies it to the segmentation of post-tonal music, namely, Olivier Messiaen’s Regards IV and XVI from his Vingt Regards sur l’Enfant Jésus. Using the idea of the center of effect(CE), a summary point in the interior of the Spiral Array, segmentation boundaries map to peaks in the distances between the CEs of adjacent segments of music. The best-case computed boundaries are, on average, within 0.94 % (for Regard IV) and 0.11 % (for Regard XVI) of their targets.
